Meaning of Mrita Sanjivini Mantra:

By means of the oblation, I set you (O patient), free to live safe from undeveloped consumption and from royal consumption; and if the seizer (the consumption) has already seized (the patient), then you, O resplendent Lord and fire-divine, set him free. (1)

If he (the patient) be of wasted life, or already dead, or he lies to the verge of death, I shall try to bring him back from the lap of Probability. I make him strong enough to live for a hundred years. (2)

I have rescued him with an oblation having a thousand eyes, conferring a hundred years, giving life for a century, so that the Lord of resplendence may conduct him beyond all harm for a hundred years (3)

Regaining your strength, O patient, live for a hundred autumns, a hundred winters, a hundred springs; may the sun, fire-divine, creator and universal God, propitiated by this century-yielding oblation, give this man back to us for a hundred years. (4)

I have rescued you, O patient, I have found you; come back again; yes, now you are young again, quite sound in body; I have obtained for you all your senses, your whole life. (5)

There is no specification about the number of recitations etc. Since it is a Vedic mantra, it should be able to give positive results. If he is nearby to you, probably you can have some water in a small non-iron pot; mix cardamom, sandal, saffron, etc and place the water pot before you. Chant this mantra and if possible, place your right palm over the vessel while reciting. May be three recitation should suffice per day. Sprinkle few drops of this water on him. Your friend should be alright at the earliest.

If you are not able to use water for any reason, as you said rightly, visualize him and pass on the benefits of this mantra to him. Visualizing is him is an advanced version of saṁkalpa.
